Is this a fuel line/hose?

[giovannie23]

97 with a 3.4
im chasing a fuel leak and there seems to be a white residue all around this hose. this is from the driver side closest to the firewall. This hose sits right behing the fuel pressure regulator ..My question is that is this a fuel hose since it smells like gas ?
If not then it has to be the injector o ring leaking gas onto it...
Any help will help
Thanks

Fuel lines are under pressure and will have either a hose clamp on them or be a tubing line connection. That hose you're pointing to at the back of the intake manifold has to be some type of vacuum line.

Sometimes when posting pictures it's helps to include one from a greater distance as well to give a better idea of the location and the components around it.

I think that is vacuum. I am pretty sure it connects to the metal tube on the lower plenum and that tube connects to a rubber hose that bends to the passenger side and into the MAF air box.

Edit: Well, on my 2002 it looks like the one that routes there...on a '97...I dunno...

Edit2: Never mind. I'm pretty sure I'm wrong.

That is a vaccuum line for sure as your fuel lines goto your injector rails..

Looks like a 3.4l intake manifold. The location looks to be on the rear corner on the drivers side. Looks to be a coolant hose.

Air Assist system hose. Connects to a "Y" whose ends go to other side of intake manifold and then to the throttle body. (that hose to throttle body is the hose that gets the check valve when supercharged.)

Yes its a air hose that connects to the y adapter
Thank you!!
I got it wraped up and so far no gas smell.. fingers crossed!
Thank you everybody for the help
